Modem 34336

The CTS option is available for 4-wire Leased Line modes. It applies only to 4-wire leased line applications using constant carrier.

•RTS — The CTS signal follows RTS.

•ON — CTS is always ON.

NOTE

The Modem also supports a CTS to EIA option, which is described earlier in this chapter under EIA OPTIONS.

The RTS-CTS Delay (CTS Delay) option is available for V.25 bis, Dumb, Leased line modes. The available RTS-to-CTS delay settings are 0, 15, 50, or 150 ms. However, the only available choices for 208A/B operation are 50 and 150 ms. If you select 0 or 15 ms, the actual delay in 208A/B mode will be 50 ms.

NOTE

RTS-to-CTS delay is not effective if the CTS option is set to ON (always ON). For V.33 operation, RTS-to-CTS delay is effective only for 4-wire leased line applications that use constant carrier.

The PHONE screen for storing a telephone number and Auto-Recovery are discussed in Sections 4.2 amd 4.3.

The LCD Intensity option is available for all modes. It allows you to use pushbutton 3 (for INC or increase) to darken characters on the LCD or pushbutton 1 (for DEC or decrease) to lighten them.

3.3.9OPTIONS ACCESSIBLE WITH SUMMARY SETUP ONLY

The twelve options described below can only be changed through the modem’s Summary Setup feature, which is explained in Appendix C.

The Wait For Carrier option is available for V.25 bis, Dumb modes. The time the modem waits for a carrier signal when origin-ating a call can be set for 30, 45, 60, or 75 seconds. (In Hayes mode, the wait-for-carrier time is determined by the value in register S7.)

The Phase Reversal in Answer Tone option is available for all modes. When enabled, the Phase Reversal in Answer Tone option signals the telephone network to turn off its echo cancelers. For virtually all applications, phase reversal should be enabled (the default setting).

The Satellite Delay option is available for 208 mode. It facilitates transmission over satellite links (but does not permit fast-turnaround operation). When the Satellite Delay option is on, RTS is inhibited for 275 ms after the answer tone stops and after the DSR signal comes on. The delay occurs at both the originating and answering modems, allowing the echo suppressors on the telephone link to be enabled.
